MokoMakefile

MokoMakefile is a fully automated way of setting up an OpenMoko development environment. It is an invaluable tool for getting new developers up and running with a build environment which is configured the same as all the other existing developers. It brings the same repeatability to build environment creation and maintenance as that which OpenEmbedded brings to the main task of actually building embedded software distributions.

Note that MokoMakefile does *not* replace bitbake, or svn, or monotone, or openembedded, or qmake, or anything else. It is a wrapper around all that to make it easy to set up and maintain a development environment that fully complies with the setup instructions published by OpenMoko. Note that you need about 12 GB of available disk space for MokoMakefile to succeed. Please check that your RAM + swap partition space is greater than 512 MB (around 1GB?).

MokoMakefile is developed by Rod Whitby - it is not an official product of OpenMoko (although I would be happy for them to pick it up and use it internally). If there is any discrepancy between the official OpenMoko build instructions, and the operation of the MokoMakefile, then you should consider the official instructions to be correct.

There is an alpha version of the MokoMakefile available at http://svn.nslu2-linux.org/svnroot/mokomakefile/branches/OM-2007.2/Makefile which builds OM-2007.2 images. You should only try this if you are an experienced MokoMakefile user. If not, then please wait for the official OM-2007.2 release to be announced.
You have to install help2man to run make openmoko-devel-image.

Before you begin

Check that your /bin/sh (ls -l /bin/sh) is not linked to dash rather than bash. Using dash will cause you pain. This is true for a standard install of Ubuntu 7.04 (at least when installing from Live CD). If your /bin/sh points to /bin/dash, correct it with (as root):

If you have previously built with dash as your sh shell then your perl compile is probably broken. One symptom is that the build will error and whine about an 'Unterminated quote string'. Another symptom is a message that says 'You haven't done a "make depend" yet!' If you get these then you need to:

make clean-package-perl
make clean-package-perl-native

and rebuild.

If all else fails then just rm -rf the perl work dir and the perl stamps. Here's an i686 host example:

5 - Start building. Before starting a lengthy make process, check in Tips section about how to make Make multicore aware. You may want to modify the build/conf/local.conf file for your target (emulation/chroot) environment:

make openmoko-devel-image

This will set up the recommended directory structure as described in Building OpenMoko from scratch, will download all the required software (from the right places with the right versions), and will immediately start building an image.

Once you have done this, you can choose to continue using the MokoMakefile to initiate your subsequent builds, or you can go into the build directory and run bitbake commands manually. The choice is yours.

Updating the environment

For easy maintenance of your build environment the following commands are available.

1 - To update the MokoMakefile to the latest version:

make update-makefile

2 - To update the OpenMoko repository checkout and the MokoMakefile patches to the latest version:

make update

3 - To make sure that any recent changes to the build directory structure have been applied:

make setup

A quick way to rebuild a new image with the latest updates:

make update-makefile && make update setup openmoko-devel-image

Reporting Problems

First, make sure that the problem is reproducible after running

make update-makefile && make update && make setup

then running

make clean-package-<foo>

(where you replace <foo> with the name of the package which is failing)

then running

make all

If you can get the error to occur three times in a row after running that sequence of commands (including the update and setup steps) three times, then feel free to report it to rwhitby in #openmoko on IRC.

Work-arounds

Work-arounds for temporary or isolated problems should be added to the Discussion page which is associated with this page. As they are fixed, they will be removed from that page.

Tips

You can reduce the amount of consumed disk space significantly by adding

INHERIT += "rm_work"

in your local.conf (e.g. ~/moko/build/conf/local.conf). This will remove the contents of each build/tmp/work/*/<package> directory after the corresponding package builds correctly.

If you an encounter an error with monotone similar to the following:

mtn: misuse: database /home/username/moko/OE.mtn is laid out according to an old schema

Then you need to upgrade OE.mtn Use the following command while in ~/moko:

# mtn --db OE.mtn db migrate

If a certain package does not build due to corrupted download or some such try to remove the sources and rebuild it.

QEMU

The MokoMakefile now has support for automatically building, flashing, and running the new Neo1973 emulator (which is based on QEMU).

Dependencies:

gcc 3.4 or 3.3 ('apt-get install gcc-3.4' in Ubuntu 7.04)

lynx ('apt-get install lynx' in Ubuntu 7.04)

netpbm ('apt-get install netpbm' in Ubuntu 7.04)

sdl-devel ('apt-get install libsdl1.2-dev in Ubuntu .704')

mkdosfs ('apt-get install dosfstools' in Debian 4.0)

“make qemu” will build qemu-neo1973, download the latest official OpenMoko images, flash the images into the virtual NAND flash, create an empty virtual SD card, and run the emulator (you still need to install the makefile as mentioned above, however).

Other targets are “make download-images” (to download the latest official images), “make flash-qemu-official” (to flash those images) and “make flash-qemu-local” (which will flash your latest locally built images), which can then be followed by “'make run-qemu” or “make run-qemu-snapshot” to run the emulator with the most recently flashed images. You can also use “'make qemu-copy-package-foo” to copy the .ipk file for package foo to the virtual SD card, and later use “'ipkg install /media/mmcblk0/file” from within the emulated Neo1973 to install the package.

Make sure you have the “lynx” and “netpbm” packages installed on your build host first.

You're also invited to read more about how to run OpenMoko under QEMU in the article dedicated to this subject.

Developing with MokoMakefile

NOTE: If using MokoMakefile with OM2007.2 then references to $OMDIR/openmoko should be replaced with $OMDIR/openembedded. Also references to tmp/work/armv4t-linux should be replaced with tmp/work/fic-gta01-angstrom-linux-gnueabi

For the following explanations $OMDIR is the directory where there Makefile puts all the stuff.

To make in-tree changes and have them built and used by qemu:

cd $OMDIR/openmoko
quilt new descriptive-patch-name.patch
quilt add trunk/src/name-of-file-to-change # do this for every file you are about to modify
...make the changes...
quilt refresh # this creates a file in $OMDIR/patches/openmoko-HEAD/ and updates the quilt series file there

Note: Do NOT use absolute paths as this confuses quilt and will get you a diff of the file against /dev/null!

To build the changes and have them used by qemu:

make build-qemu
make flash-qemu-local
make run-qemu

If you want to modify applications instead of the openmoko toolchain, this is what you have to do (example: openmoko-messages):

If you want to add an application to your openmoko distribution, do this:
All file edits should be done using quilt as described above. That way a patch can easily be submitted to the openmoko project.
First, create a directory that will correspond to your package and edit a .bb file in there:

inherit autotools - The package can be compiled by './configure && make && make install' so we tell MokoMakefile to do it this way.

SRC_URI = ... - This is the download location of the package source. It's imperative that the tar.gz contains a directory called packagename-packageversion (in this case: mycoolpackage-1) so that MokoMakefile can find it automatically or the build will fail.

This is not all. We also need to tell MokoMakfile that it needs to build and include the package in the image. To do this, do

$OMDIR/openmoko# quilt edit trunk/oe/packages/tasks/task-openmoko.bb

Here, increase the value PR by one and add mycoolpackage \ (with the backslash!) just before the line reading # update-alternatives \.

Now run

quilt refresh
cd ..
make update all

And if everything's alright you should now have an OpenMoko image to flash to your phone or run in qemu as described above.

Testimonials

MokoMakefile is recommended by 4 out of 4 new developers on #openmoko, with testimonials such as "For some reason last night I couldn't get my manual install of everything to work (bb complained about my bbpath I think) ... but with your makefile, it works great!", "MokoMakefile rocks!", and "Wow this build system is nice - it just seems more polished than my gumstix toolchain buildroot system".
